[0032] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0033] This application provides a composite high-strength steel wire that can solve the problem of low reuse rate caused by common defects such as steel strand corrosion in related technologies.

[0034] See Figures 1 to 3 As shown, this application embodiment provides a combined high-strength steel wire, comprising:

[0035] The high-strength steel wire 10 includes high-strength steel wire segments 11 of a predetermined length. Each high-strength steel wire segment 11 is a single wire with a diameter greater than 20 mm. The length and diameter of the high-strength steel wire segments 11 can be specifically set according to actual needs. The tensile strength of the high-strength steel wire 10 is as high as 1200 MPa to over 1580 MPa, far exceeding the tensile strength of ordinary steel bars (320 MPa), demonstrating high strength.

[0036] The wire joint 20 includes an open joint 21 and / or a closed joint 22 respectively fixedly connected to the ends of a high-strength steel wire segment 11. The open joint 21 and the closed joint 22 are detachably connected to each other. The two ends of a single high-strength steel wire segment 11 can be an open joint 21 and a closed joint 22, or both ends of a single high-strength steel wire segment 11 can be either an open joint 21 or a closed joint 22. However, two high-strength steel wire segments 11 connected to each other are connected by an open joint 21 and a closed joint 22.

[0037] In this embodiment of the application, the combined high-strength steel wire uses high-strength steel wire 10 instead of steel strand 12. The high-strength steel wire 10 is composed of multiple high-strength steel wire segments 11. Each high-strength steel wire segment 11 has higher strength and is thicker than the single wire diameter of the steel strand 12. This can reduce the number of single wires in a single steel strand 12, effectively reduce the area that is prone to corrosion, and improve durability and turnover rate.

[0038] In addition, an open connector 21 and a closed connector 22 are provided at the end of the high-strength steel wire segment 11. The open connector 21 and the closed connector 22 are detachably connected to each other. According to actual needs, the open connector 21 and the closed connector 22 can be used to assemble the high-strength steel wire segment 11 into high-strength steel wires 10 of different lengths. The installation is simple and the operation is more convenient.

[0039] In some alternative embodiments: see Figures 1 to 3 As shown, this application embodiment provides a combined high-strength steel wire. The open joint 21 of the combined high-strength steel wire includes a steel sleeve connecting the end of the high-strength steel wire segment 11, and ear plates symmetrically arranged on the steel sleeve for connecting the closed joint 22. The ear plates have connection holes, and the ear plates and the steel sleeve are integrally formed by casting.

[0040] The closed joint 22 includes a steel sleeve connecting the end of the high-strength steel wire segment 11, and a connecting plate connected to the steel sleeve for connecting the two ear plates of the open joint 22. The connecting plate has a connecting hole, and the connecting plate and the steel sleeve are integrally cast. The wire joint 20 also includes a cylindrical pin or bolt connecting the open joint 21 and the closed joint 22, and the cylindrical pin or bolt passes through the connecting hole between the ear plate and the connecting plate.

[0041] In some alternative embodiments: see Figures 1 to 4 As shown, this application embodiment provides a combined high-strength steel wire. When the length of a single high-strength steel wire segment 11 cannot meet the length requirement, the combined high-strength steel wire 10 is provided with multiple high-strength steel wire segments 11. Two adjacent high-strength steel wire segments 11 are connected to each other and extended sequentially through open joints 21 and closed joints 22.

[0042] When a single high-strength steel wire 10 cannot meet the stress requirements, multiple high-strength steel wires 10 can be used to form a bundle of high-strength steel wires 10 according to the stress requirements. The high-strength steel wire 10 is provided with multiple high-strength steel wire segments 11. Two adjacent high-strength steel wire segments 11 are connected to each other and extended sequentially through open joints 21 and closed joints 22. The steel wire joints 20 between the high-strength steel wire segments 11 arranged in parallel are staggered.

[0043] In some alternative embodiments: see Figure 5 and Figure 6 As shown in the embodiment of this application, a composite high-strength steel wire is provided. This composite high-strength steel wire also includes a steel strand 12 connecting to the high-strength steel wire 10. One end of the steel strand 12 is provided with a connector 23 connecting to a closed joint 22. The connector 23 includes an anchor plate connected to the steel strand 12, and two symmetrically spaced hinge plates connecting the anchor plate. The connecting plate of the closed joint 22 is located between the two hinge plates and is connected to each other by a cylindrical pin or bolt.

[0044] In some alternative embodiments: see Figure 7 and Figure 8 As shown in the figure, this application embodiment provides a combined high-strength steel wire, which also includes a steel wire rope 13 connecting the high-strength steel wire. One end of the steel wire rope 13 is provided with a shackle 24 for connecting to a closed joint 22. After the pin of the shackle 24 passes through the connecting plate of the closed joint 22, it connects the steel wire rope 13 and the high-strength steel wire 10 together.

[0045] In some alternative embodiments: see Figure 2 and Figure 3As shown in the embodiment of this application, a composite high-strength steel wire is provided. The high-strength steel wire segment 11 is connected to the open joint 21 and the closed joint 22 integrally by welding, threaded connection, or casting. Welding or threading the high-strength steel wire segment 11 to the open joint 21 and the closed joint 22 improves on-site assembly efficiency. When the high-strength steel wire segment 11 is integrally connected to the open joint 21 and the closed joint 22 by casting, the structural strength is better and the safety performance is higher.

[0046] Working principle

[0047] This application provides a combined high-strength steel wire.

[0048] Therefore, the combined high-strength steel wire of this application uses high-strength steel wire 10 instead of steel strand 12. The high-strength steel wire 10 is composed of multiple high-strength steel wire segments 11. Each high-strength steel wire segment 11 has higher strength and is thicker than the single wire diameter of the steel strand 12. This can reduce the number of single wires in a single steel strand 12, effectively reduce the area that is prone to corrosion, and improve durability and turnover rate.

[0049] In addition, an open connector 21 and a closed connector 22 are provided at the end of the high-strength steel wire segment 11. The open connector 21 and the closed connector 22 are detachably connected to each other. According to actual needs, the open connector 21 and the closed connector 22 can be used to assemble the high-strength steel wire segment 11 into high-strength steel wires 10 of different lengths. The installation is simple and the operation is more convenient.
